~I'd vote for including https://github.com/ipfs/go-ipfs/pull/6300 (base32 for cidv1) in this release~. Done.

Works for me but we'll need to wait for js-ipfs.

I'd like to see https://github.com/ipfs/go-ipfs/pull/6266 included in this if possible. I can certainly set this myself, but having it as an automated increase for others is probably a good idea until we figure out what's causing https://github.com/ipfs/go-ipfs/issues/6237

Also, I'm not sure if there's a fix for https://github.com/ipfs/go-ipfs/issues/6271 yet, but having this functionality working is one of the most important features Pinata needs right now.

@Kubuxu please can we get some bullet points on what is already in this release and what's left to do?

New blocker: https://github.com/libp2p/go-libp2p/issues/644. Yay!

Hi,

Have you planned to upload the official docker image with the tag name of this release v0.4.21 to Dockerhub? Thanks.

[olizilla]

Dockerhub has failed to trgger the build for the v0.4.21 tag. We're looking into it. In the mean time the release tag can be used.
